jj-clean

I have just started using jj and want to start using it on top of my currentn git repos, inclusing some that I collaborate on others with. One of the things I notices is that when I run tig --all, jj completely blows up my repo. This is because jj puts a git refs on absolutely everything so that git won't garbage collect it. Which includes working copy commits that I am never going to go back and look at, but jj needs to keep them around so that the undo system can work (at least I think that's why).

So, this script is my hack to clean out all of these refs from the .git/refs directory so that they don't show up in a normal git tree viewer. There may be a more native way to do this, but like I said, I just started using jj...

This script should probably not be used by anyone other than me right now, it does not allow for any configuration.
